Beit known thatrI, GEORGE E. SMALL, a Citizen oi' the United States, residing at Richmond Hill, in the county of Queens and telt-ate of New York, have invented certain Stn improved construction of reinforced concrete kor cement hollowrwalls in which an improvedslab 4or block of this character isl utilized in the building of such a structure,

thepresent improvenient-beinga division of l tiy contcmporaneously 'pending a pplicatioii,l

Serial NUQQGZOS, filed May 6, 191.`

One of the objects of the invention is the provision of an improved reinforced slab or block which may be manufactured at a very liow cost and which, with companion blocks,

may be readily assembled and so intei'loclied one With another that the structure will have the appearance of a monolith.

Another object of the invention is the provision of improved reinforcing 'means for the slabs or blockswliich reinforcing means may alsobe utilized asa ineansfor connecting or locking' one blockl with com panin l'-blo'cks, whereby the several bloi'rks.

whenfassembled aref so bound togethe'v `nat intervals with hollow spaces which may be 40 iadily `iritilizedfor 4the a Vervsolid 'reinforced structure is obtained,`

and y reason ofthe-improved formation ofthe blocks the structure is 'provided at passage of pipes, conduits, etc. i

Anotlier object of the invention is the pro visionofan improved slab or block so constructed"andyrei'nforced and' provided with improved means for 'unitingA it with conipanionblocksithat such vbloclcor slab may be made of greatqength, so that in Ymany `iu stancesr it ina-y be 1o f siiilicieiit length to reach the fullheiglit of the-structure on the out l0 side: of ther-*building apndvtheheight,` from floor to ceiling on the inside. i

BLOCK 0R' SLAB FOR BEINFORCED HOLLOW-WALL C DNSTRUCTION.

I atelited Feb. 6, 1917.

view of one side of one of the slabs 0r blocks which may be' utilized with this irn-` proved coi'istruction; Fig. 2 is a sectional view illustrating the inannei' of assembling the slabs shown ii Fig. l to forni hollow reinforced walls; Fig. 3 is an enlarged pai-tl)-Y scctional vi ew illustrating a' portion of the structure sliown in Fili'. 2; Fig. Ll; is a partly vertical iectiona'l view showing a portion of a block interloclied with the beam portioniof another block and. also separate ero these improved slal is and having an attached floor.

Similar charactirs of reference indicate corresponding par s in the several figures of the drawings.

As liercinbefore stated, each of the cement or concrete blocks or slabs 2 will usually be of a length to corr :spend with the height oity the structure, and in Fig. 1 in the present instance the slab .is shown of a length about seven and a half ti mos that of its width. It will, of course, be indcrstooch however, that the 'length of the slab orblock will correspond either with tlionhcight of the structure for with the distan( e between the Ceiling and the floor and ma) be made of any `length within reasonable limits.

In the referri ed form thereof her-ein showniand i escribi d each of the slabs of the iorm shown in Fig. 1 comprises a pairof 'oppositely'extendii ig wing portions 3 and 4,

which may be mad i, if preferred, ofV slightly tapered form, which wing portions are united in fthe `pi esent instance centrally thereof by a lengt liwisc extending body .or beam portion ser ving to reinforce the slab:-

or blocle'and which beam portionis proV Vvided at intervals t liroughout its length with inwardly extending; recesses 6,- which recesses coinn'iunicatc one v `-ith another and with the ends of the bloclcliy sections ofY pipe 12 lo4- cated in place duri: ig the casting of the slab. These recesses 6 ari for the reception of the means for interloc :ing the several slabs to- 60 or any suitable fil ing materialwliich it may Vss .23 having rabbeted ture and ether. When slabs of this form are used or floor construction they may be further reinforced by reinforcing bars 7, 8, see Figs. 3, 5, 6, and 7. These, however, are not necessary when the slabs are used for the construction of side Walls. Each of these slabs is at intervals reinforced bythe provision of a metal rod or bar 9 extending through the said wings, andcertain of these reinforcing rods are located to have the inner ends thereof adjacent to a recess 6 andare so bent as to form a loop 10 extending into such recess- 6. These same looped rods at the ends or sides of the slab project therefrom to form loops 11, which loops'are lof sufficient length to project into the recesses 6 hereinbefore descrlbed of companion slabs.

In assembling the several slabs made in the manner described, itwill be observed that in Figs. 2 and 3 the outer and innera rows 13 and 14 of slabs break joint with each other and in such manner that the recesses 6 of each slab receive a pair of loops 11 of a companion pair of slabs into Aoverlapping relation with the loop l0, whereby when assembled a locking rod 15 can be inserted through the several sets of loops lengthwise of theslab and thusr interlock the several slabs or blocks-together.i "For the purpose of facilitating the insertlbn of this rod the sectional portions of pipe 12y hereinbefore .referred to areI located in the I*slab during the casting `thereof,and the pipe at each end of the slab may be internall threaded, as at 16, for the Areception of a 1i ting eye-plug 17, see Fig. 4,

whereby the slab may be readily hoisted into position; --As stated, the reinforcing rods 9 are provided withv loops at intervals, these intervals corresponding tov the position of the recesses 6. At other intervals reinforcingrods may be used, which, however, it is unnecessary to provide with loops. .When the walls are assembled at right angles to each other a corner slab 20 of substantially the vform shown in Fig. 3 may be used, this corner slab likewise havin a pair of wing portions 21 and 22 meeting 1n a body portion ortions 24l for the reception of the' side e ges of a air of outer wall blocks. This corner bloc is likewise provided with recesses at intervals .by means of which the loo s of companion blocks may be interlocked wlth the loop of the reinforcing rodV of the corner block in the 'manner hereinbetorc described. 1

From'Il the foregoing it will 'be observed Athat the blocks are'so interlocked 'together that they ractically forma unitary strucso provide hollowspaces between themV for the rece tion of pipes or conduits be desired to. insert therein. By means of l thepipes hereinbefore. referred to, after, the

sl'abs are assembled grouting may b run into theev'eral recesses, .thus a. solid relone slab 'yith companion floor reinforcing bars 7 and 8 are preferably used. In Fig. 6 the blocks are shown assembled in the manner herei'nbefore described, to'

form a combined floor and ceiling: In Fig. 6, however, an outer row of'blocks only is used to form a floor, to which is attached a ceiling, such blocks being connected in the same way as shownl in Fig. 7, where they form a ceiling to which is attached a floor and'have their reinforcing rods twisted together, as at 30, to hold such blocks in position. In both of these instances nailing strips 3.5 are secured to the concrete oi' cement blocks by suitable bolts'located at intervals, and to these strips may be secured metal lathing, as in Fig.' 6, or a wooden Hoor, as in F 1g. 7, the hollow spaces 40 being utilized, as hereinbefore stated, either for the location of gas iping, conduit for electric light Wiring, or or the carrying of hot water air ducts or steam heating appliances if so desired, and these spaces, when the structure is utilized as a floor, may be filled with sand, sawdust, asbestos or any other sound resisting material, therebyl providing a sound- -proof floor, which is vespecially desirable in apartments.

` In assembling the several slabs to form a VWall structure, molding pieces of. cement or concrete, such as 50, 60 and 70 may be used,

and each of these is likewise reinforced by metal rods 71 having projecting ends 72 so located as to overlap companion blocks, as at 73. In some instances these rods may be twisted together,l as atY 74.

Theheight of one oor having been constructed inthe `manner hereinbefore described, this isy repeated throughout the height of the buildin y f course it will e understood that the outer faces of vthe walls and faces of the ceilings may. be provided with a cement coatin or stucco, or the'slabs may be pebble dashe when they a're'frst molds, as may be preferred.

It will also be observed stancethe preferable way to maintain and secure the. reinforcing rods in position vis to l provide such reinforcing rods with loops or eyes throu h which may extend d rod/or,

bar. It w1 l also be understood that that/vafof (great length as compared w th its Width,-

the improved manner/ interlocking removed from the that in each l siehe, whereby 'l 13 unitary structure is provided and an irnproved hollow reinforced Wall constructionll obtained.
